[Pharo-project] Issue 3815 in pharo: Filing in Class comments raises an error

by pharo＠googlecode.com

Status: Accepted Owner: ryd...(a)gmail.com Labels: Milestone-1.2 Milestone-1.3 New issue 3815 by ryd...(a)gmail.com: Filing in Class comments raises an error http://code.google.com/p/pharo/issues/detail?id=3815 Broken by SourceReference changes. ChangeRecord >> fileIn directly notifies deprecated RecentMessageSet. It seems to me like the #comment:stamp: call should correctly update RecentMessageList through the SystemChangeNotifier, and the calls could simply be removed. Need external confirmation of this though, as I have not beeen involved, and have no idea what the implications/consequences of RecentMessageSet deprecation really is. PS. We need tests for fileIns of different kinds, all tests passing for 1.2 without catching stuff like this is bad :)

Btw, we discussed a bit of this today with Henrik, and first thing i think people should do, in order to make it more secure is to disable external module loading mechanism. Declaring that standard VM is more secure if you don't ship it with _external_ modules (like FFI) sounds like a joke. So, what i'd like to ask is, that if everyone feel a day-to-day need for using things like FFI or OSProcessPlugin we should make it available by default and out of the box. And for those, who concerned with low security there is always an options to improve it, like hiring people to develop a custom VM based on default one, where all security problems is addressed properly. So, i don't see why we should constrain ourselves with things we use and need, only because in eyes of someone it doesn't looks secure enough. > Dave > -- Best regards, Igor Stasenko AKA sig.

Linux certainly allows that mistake.

Re: [Pharo-project] The current status of OSProcess

by David T. Lewis

Hi Igor, I think it is good to make OSPP (and AioPlugin and XDisplayControlPlugin where appropriate) available in all distributed VMs, but in some applications they provide too much access to the operating system, so it is good to have them as external modules so that people who do not want them on the system can delete the modules. So I think it is best to treat it like FFI, it is there if you want it but can be removed if you are doing some sort of application where the user should not have easy access to the OS functions.

Cheers, Henry PS: http://forum.world.st/Is-it-possible-to-setup-Russian-fonts-in-Pharo-Cog-VM… , you can include the FT2Plugin from a standard vm somewhere Cog will find it, and it should work. Really should make this a FAQ entry :)

Re: [Pharo-project] The current status of OSProcess

by Igor Stasenko

David, i don't remember the outcome of last discussion about it, but i heard some people proposed to add the OSProcess plugin to be built as internal one. Or at least ship it with every VMs, same as FFI plugin. On 12 March 2011 20:53, David T.
